title: Matrix Free approach for Raviart-Thomas anisotropic Tensor Product Finite Elements creator: Mehta, Saurabh subject: ddc-004 subject: 004 Data processing Computer science subject: ddc-510 subject: 510 Mathematics description: In this thesis, we develop techniques for fast, efficient cell based operator evaluation of Raviart-Thomas finite elements and thereby extend the existing implementation of matrix free framework in deal.ii. The extensions allow the framework to also support anisotropic vector-valued finite elements in addition to existing isotropic Lagrangian finite elements. Tests on finite element operators in divergence conforming spaces for Mixed diffusion equation and Stokes equations show that the method is sufficiently accurate (relative error 10e-16) and for RT2 is already twice as fast as corresponding sparse matrix based solution. date: 2018 type: Master's thesis type: info:eu-repo/semantics/masterThesis type: NonPeerReviewed format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/24230/8/MehSa_Thesis-1.pdf format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/24230/14/MehSa_Thesis_old_version.pdf identifier: DOI:10.11588/heidok.00024230 identifier: urn:nbn:de:bsz:16-heidok-242308 identifier: Mehta, Saurabh (2018) Matrix Free approach for Raviart-Thomas anisotropic Tensor Product Finite Elements.
